Scarcely were they enjoying the cool rest the water gave their hot, tired limbs, when they were seized and swallowed by two kurreahs. Having swallowed the girls, the kurreahs dived into an opening in the side of the spring, which was the entrance to an underground watercourse leading to the Narran River.
